Abstract
: The existence of this radioactive isotope, reported half-life of 13.4 days, has not been confirmed. : This isotope of 3.92±0.02 hours half-life has been produced by the reactions , and . Positrons of 1.13 Mev and gamma-rays of 1.65 Mev are emitted. The ratio of the number of positrons to gamma-rays is four. : One of the isomers of decays with a half-life of 3.92±0.03 hours. The positrons and gamma-rays have the same energy; namely 1.33 Mev. Three gamma-rays per positron are emitted. Absorption measurements in aluminum and in beryllium indicate characteristic x-rays. The other isomer of has a half-life of 2.44 days. The genetic relation of the isomers of has been confirmed.
